COFFEE-URN.

Specification of Letters Patent.

T0 at whom, it may concern.-

Be it known that I, ROBERT M. BAMFORD, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Coffee-Urns, of whichthe following is a specification.

My invention relates to coifee-urns for use in hotels, restaurants, andsimilar locations, and relates especially to an arrangement andconstruction of parts whereby all settlings, sediment, &c., areprevented from being .drawn off with the coifee or other beverage andwhereby the device may be readily and easily cleansed.

In the accompanying drawing the figure represents a section of acoffee-urn or similar vessel provided with my improvement andillustrates an exemplification of my invention as applied to this classof devices.

Referring to the drawing, the referenceletter a indicates the outercasing of a suitable cofiee or tea urn, such as are now generally usedin hotels, restaurants, and similar places, the same being generally inthe form of an upright cylinder. The casing is provided near its lowerend with the usual bottom wall or partition I) and is supported at itslower end in any suitable manner now well understood. The u per open endof the casing or cylinder is c osed by a suitable cover 0. Within theouter casing a suitable inner casing d is supported in any .desiredmanner, preferably by having a top flange 6 extending outwardly aroundits open upper end and adapted to rest upon the top edge of the outercasing a. The inner casing d constitutes the chamber or receptacle inwhich the tea, coffee, or other beverage is made and preferably issomewhat smaller in cross-section or diameter than the outer casing 01,in order to provide a suitable intermediate water-j acket between thetwo shells. The inner receptacle d is of the usual shape and size to fitwithin the outer casing in the manner now well understood in the art,and its lower portion is tapered or cone-shaped and preferablyterminates in a suitable discharge-outlet, as

shown in the drawing, at its apex. The out.- let is provided with asuitable pipef, which leads out through the outer casing, where it isprovided with a suitable plug or cap g, which may be readily attachedthereto and detached therefrom. The outlet pipe is tapped at anysuitable point in its length by a draw-ofi' pipe h, which also projectsthrough the outer casing and terminates in the usual faucet likeconstruction, as shown in the drawing, for the purpose of drawing thetea, cofiee, or other beverage. The draw-off pipe k may connect with thepipef in any suitable manner; but I prefer to form the inner end of thepipe h with a downwardly-inclined pitch or sectionas shown, for example,at 'ithe purpose of this construction being to prevent any settlings orforeign substance to pass into the draw-off pipe when the device is inuse.

In practice the water-jacket between the shells or casings is filled anda suitable flame is applied beneath the receptacle, as shown in thedrawing, for the purpose of heating the water in the jacket. The tea,coffee, or other material to be prepared is placed within the innerchamber or receptacle, this material usually being confined within acloth bag, together with the necessary amount of water to be employed,and the prepared beverage is then drawn OK as occasion requires throughthe faucet. In the event the bag bursts or for other reason sediment orforeign substance gets into the inner chamber or receptacle the grounds,settlings, and other sediment will pass down into the outlet-pipe f,from which they may be readily withdrawn when the cap or plug isremoved, and none of this foreign materialwill be drawn ofl through thefaucet by reason of its lodgment within the passage through theoutlet-pipe. The pitch or inclination of the draw-off pipe, as at i,serves in this connection to insure against the passage of any foreignsubstance through the faucet with the beverage.

In addition to the advantages which are apparent from the abovedescription it is ob vious that by the'construction here shown anddescribed I provide a device of this class which is readily and easilycleaned or washed. It will be seen that by removing the plug or cap ofthe outlet-pipe f water will freely and unobstructedly flow through theinner chamber, which on account of its shape permits of thp1 water tofreely flow through from end to en In the present construction in casethe bag holding the coffee, tea, &c., shall burst the material may bereadily withdrawn through the outlet-pipef without in any manner clogging the draw-off pipe. For this reason my construction is advantageousover other devices, in which in such case it is necessary to dip thecontents out of the receptacle and the draw-off pipe is clogged.

Having described my invention, What I desire to secure by Letters Patentand'claim 1s In a device of the class described, in combination, anouter receptacle having a bottom, an inner receptacle supported by theouter receptacle and provided with a substantially cone-shaped bottomterminating in a discharge-outlet, a downwardly-extending outlet-pipeconnected to the dischargeopening and passing through the Wall of the
